ANTIISLIPPING DEVICE FOR AUTOMOBILES- T a whmn it may concern:

Be it known that we, EDWARD NYE' and Ammo GRUEsBEoK, citizens of the United States, residing at Charlotte, in the county of Eaton and State of Michigan, have invented certain new and useful Improvements in Antislip ing Devices for Automobiles, of which t e following is a specification, referenoe being had therein to the accompanying drawings.

This invention relates to im ro'vements in antislip ing devices for vehic e-wheels, and particul arly the wheels of automobiles or horseless carriages.

The object of the invention is the peculiar construction of a shoe or gripping member pneumatlc or cushioned tire of a wheel.

Another object of the invention is the provision of means for facilitating the passage of a vehicle over slippery or icy ground and in climbing or descending a grade.

With these and other objects in view the invention consists of certain novel construe-- tions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed. 1

In the drawings, Figure 1 is a fragmentary perspective view of an antislipping device positioned upon the tread of the tire of the wheel. Fig. 2 is a fragmentary top plan view of an antislipping device applied to a wheel as illustrated in Fig. 1. Big. 3 is a top plan view of one of the shoeor gripping members employed in constructing the antislipping device, while Fig. 4 is a view 1n side elevation of one of the shoes. Fig. 5 is an embodiment, shown partly in longitudinal section, of the connecting means for the shoes or gripping members. Fig. 6 is another embodiment of the connecting means for the shoes, and Fig. 7 is still another embodiment of the connecting means.

Referring to the drawings by referencenumerals, 1 designates the body portion of the shoe or gri )ping member,-which body portion is upwardly bowed, and its ends terminate in horizontal parallel flanges 2 2. Each flat flange 2 is provided, preferably, with a pair of vertical apertures 3 3, the apertures 3 being formed upon op osite sides of a vertical reinforcing-rib 4, wiich rib is integral wlth the body 1 and said flanges 2. The rib 4 extends longitudinally of the body portion 1 and transversely of the flanges 2, thereby greatly strengthening said flanges 2. The

Specification of Letters Patent. Application filed October 11,1906. Serial No. 338,522.

- body portion 1 is provided with a smooth inner surface 5, Which-surface conforms to the shape of the tread of the tire 6. The body portion 1 and rib 4 are formed at an obtr-se angle to the parallel flanges 2 whereby the shoe'is ositloned at an obtuse angle to the tire 6 of the wheel7. An important and material advantage is obtained by the peculiar structure and positioning of the shoes or gripping members, because while the rib 4 of each shoe is capableof grippi the ground as the wheel revolves, the same as if said shoe was positionedtrans ersely of the 'wheel, still the rib 4 .is lifted easily out of the ground, because the antislipping device hassomewhat of a screw action in engaging and disengaging the ground when the wheel is revolved. -Our shoes or rip ing members are not synchronously l fte off of the ground, as would be the case if they were positioned transversely of the tire, but are gradually lifted fromone end to the o posite end, thereby obviating the bodily lifting of the entire shoe or shoes, which would-cause a strain upon the device in many cases as, for instance, if the vehicle was traveling in mud.

In the accompanying drawings we have shown different embodiment of the connecting means for joining the shoes together, which connecting means also serve to retain or attach the shoes to the tire.

Referring to Fig. 5, the attaching device comprises bolts 8 and 9. The bolt 81s provided, preferably at one end, with a loop 10, while its opposite end is screw-threaded. The bolt 9 is provided at one end with a hook I 1, while its opposite end is also screw-threaded. Upon the screw-threaded ends of the bolts 8 and 9 is a rotatably-connecting member or turnbuckle 12. The bolt 9 is preferably permanently secured within an aperture 3 of a flange 2, while the hook 11 is removably securedwithinan aperture 3 of the flange 2 of another shoe. By reason of this structure of the connecting or coupling device a pair of shoes can be quickly connected,

lDO

and if all of the shoes of the antislipping device are connected upon the tire the 'inner faces 5 of the bodyortions 1 of the shoes can be caused to tig tly clamp or grip the tread of the tire by adjusting oneor more of the turnbuckles 12. It is to be noted that in the embodiment depicted in Fig. 5 we have provided adjustable attaching means for connecting each two of the-shoes and also that this attaching or coupling means-constitutes an adjustable locking device for holding the shoes upon the tread and also causing said shoes to tightly grip the same.

In the embodiment depicted in Fig. 6 each two contiguous shoes are connected by a plurality of links '13. The links constitute a short chain, which is positioned away from the tire by reason of the flanges 2 2. It is to be noted that the chains in this instance are not positioned below therim of the wheel 7. It will be obvious that by removing a link the chain can be tightened, or, vice versa, a link added for increasing the size of the antislipping device.

In the embodiment depicted in Fig. 7 a sin; gle link 14 is employed for connecting each two shoes or gripping members at each end.

7 This link 14 is provided, preferably, with a straight body and with loops 15 15, formed What we claim is 1. The combination with a wheel, of a shoe carried by said wheel, said shoe comprising a body portion, flanges formed at the end of said body portion, a rib extending longitudinally of the body portion and transversely of said flanges and integral with said body portion and flanges.

2. The combination with a wheel, of a shoe carried by said wheel, said shoe comprising a body portion provided with flanges, a rib integral with said flanges and body portion, each flange provided with apertures formed upon opposite sides of said rib, and

means for securing said shoe upon said wheel.

3. A device of the character described, comprising shoes, each shoe comprising a body provided at its ends with flat, horizontal flanges, a rib integral with said body and flanges and extending longitudinally of the body and transversely of the flanges, each flange provided with vertical apertures formed upon opposite sides of said rib, and

coupling means positioned within the. apertures of the flanges of all of'said shoes.

4. A device of the character described, comprising shoes, each shoe comprising a body provided at its ends with integral horizontal flanges, a rib integral with said flanges and body, each flange provided with vertical a ertures formed upon opposite sides of said ri and a pair of coupling devices for each two contiguous shoes, each device compris ing bolts and a turnbuckle threaded thereon, each bolt provided with a hooked end posi tioned within a vertical aperture of a flange.

5. A device of the character described, comprising a body provided with horizontal flanges, each flange provided with vertical apertures, coupling devices for each two contiguous shoes, each of said coupling devices comprising bolts, one of said bolts provided with a looped end ositioned in one'of the vertical apertures o a flange, the other bolt provided with. a hook positioned within a vertical aperture of the flange of another shoe, and said hook adapted to be quickly lifted from its engagement with said flange, and a turnbuckle threaded upon the contiguous ends of said bolts.

6. A device of the character described, comprising shoes, means connecting said shoes, each shoe comprising a longitudinallycurvedbody terminating at its ends in horizontal flanges, a rib integral with said body and flanges and extending contiguous to the outer edges of said flanges, and said flanges provided with apertures formed upon opposite sides of said rib.

7. A device of the character described, comprising shdes, means connecting all of said shoes, each shoe comprising a curved body terminating atits ends in flat flanges; a

rib integral with said body and flanges andtermirrating near the outer edges of said flanges, said rib provided with an upper, straight, horizontal tread. edge, and each flange provided with an aperture. near each. end.

8. As a new article of manufacture, a shoe for an antislipping device formed from a single piece of material, and comprising a body rovided with arallel, flat flanges, the body ormed at an o tuse angle to said flanges, a reinforcing-rib integral with the flanges and body, and each flange provided with a pair of vertical apertures.

In testimony whereof we hereunto afiix our signatures in presence of two witnesses.
